Abstract
A generalization of the materials of a comprehensive paleogeographic study in the ancient glacial region of the Russian Plain is aimed at establishing regional features of the geomorphological structure and patterns of spatial variability of indicators. For these purposes, geological and geomorphological zoning of the territory was carried out on the basis of a systematic approach and under the control of paleogeographic expertise. On the compiled map, the territorial divisions are highlighted: against the background of different age paleogeographic zones, 4 geological provinces and 14 geologic-geomorphological regions are distinguished. Their complex characteristics are obtained by the totality of the leading geomorphological processes. Particular attention is paid to the study of the glacial relief, which plays an important role in paleogeographic reconstructions of this area. Marginal zones infrastructure of the ice sheets of different ages has been studied in detail, which makes it possible to make more exact the maximum and stadial boundaries of the Moscow and Kalinin ice sheets. Thus, regional features of the structure and composition of the morpholithogenic basis of landscapes are established. The laws of its formation are confirmed: geological and geomorphological heredity and paleogeographic conditionality. The study of regional features of the geomorphological structure of the ancient glacial region makes a significant contribution to the reconstruction of the glacial rhythm of the Pleistocene. The results of integrated geologic-geomorphological zoning facilitate the regional targeted estimation of the state of geoecological stability of geosystems and make it more justified.
